UNEXPECTED CONTAINMENT LINER PENETRATION FOUND

"On October 4, 2013, during the Beaver Valley Unit 1 refueling outage, a planned visual examination of the interior containment liner and coatings was being performed. The containment design consists of an interior steel liner that is surrounded by reinforced concrete. An area approximately 0.4 inches by 0.28 inches was discovered that penetrated through the containment steel liner plate. 




"With the plant currently shut down and in Mode 6 the containment as specified in Technical Specification 3.6.1 is not required to be operable. The cause of this discrepancy is currently being evaluated.
  
"This is reportable pursuant to 10 CFR 50.72(b)(3)(ii)(A). 

"The Site Resident Inspector has been notified."
